2. What is JavaScript?
• A scripting language developed
by Netscape to enable Web authors to
design interactive sites.
3. Scripting Language ?!?
• A high-level programming language that
is interpreted by another program
at runtime rather than compiled by the
computer's processor as other
programming languages
(such as C and C++) are.
4. JavaScript (JS)
• is an interpreted computer programming
language. It was originally implemented
as part of web browsers so that client-
side scripts may interact with the user,
control the browser,
communicate asynchronously and alter
the document content that is displayed.
5. web browsers
• A web browser is a software application
for retrieving, presenting and traversing
information resources on the World Wide
Web.
6. JS Birth @ Netscape
• JavaScript was originally developed in Netscape,
by Brendan Eich. Battling with Microsoft over the
Internet, Netscape considered their client-server
solution as a distributed OS, running a portable
version of Sun Microsystems' Java. Because Java
was a competitor of C++ and aimed at
professional programmers, Netscape also wanted
a lightweight interpreted language that would
complement Java by appealing to
nonprofessional programmers, like Microsoft's
Visual Basic. (see JavaScript and Java)
7. • Developed under the
name Mocha, LiveScript was the official
name for the language when it first
shipped in beta releases of Netscape
Navigator 2.0 in September 1995, but it
was renamed JavaScript when it was
deployed in the Netscape browser version
2.0B3
8. • The change of name
• from LiveScript to JavaScript
roughly coincided with Netscape adding
support for Java technology in
its Netscape Navigator web browser. The
final choice of name caused confusion,
giving the impression that the language
was a spin-off of the Java programming
language, and the choice has been
characterized by many as a marketing
ploy by
9. • Netscape to give JavaScript the cachet of
what was then the hot new web
programming language. It has also been
claimed that the language's name is the
result of a co-marketing deal
between Netscape and Sun, in exchange
for Netscape bundling Sun's Java runtime
with its then-dominant browser.
